I am only conditionaly interested in beta testing program depending on changes made in performance related topics, but unfortunately I didn't find any detailed information about those. Does someone have more info and be so kindly to tell/show more?
Briefly description on ASA site is not very helpful

Performance - performance is a focus with every SAP Sybase SQL Anywhere release and it will be no different with Nagano. In addition to keeping up with advances in hardware, we also respond to customer feedback for improvements"

If you sign up for the beta test, you will get access to the web Help without having to download or run the software itself, and in that web Help there is some discussion of the performance enhancements.
